Advanced Working Principle
Our permanent magnet frequency conversion air compressor is a masterpiece of engineering. Equipped with a state-of-the-art pressure sensor, it instantaneously detects system pressure and air consumption in real-time. Through precise electric and frequency converter control, it dynamically adjusts motor speed while consistently maintaining constant torque. This ensures that system pressure is regulated and output precisely matches demand. As air consumption decreases, the compressor intelligently reduces rotational speed, minimizing compressed air output. Conversely, it speeds up to increase air supply when demand rises, effortlessly maintaining stable system pressure.
Utilizing pioneering vector control technology, our compressor operates flawlessly across a broad range of speeds. This innovation minimizes motor temperature rise while ensuring sufficient torque to drive the air compressor smoothly. The motor current, composed of torque and other vector control components, is expertly optimized to determine the exact current values required. This technology compensates for voltage drops, enabling the motor to deliver maximum torque without increasing current, ensuring peak performance at all times.
